Quote of the day by Oscar Wilde : ‘Some cause happiness wherever they go; others, whenever they go.’ The line looks at two types of impact a person can have on others. One group brings happiness when they arrive. The other creates a sense of relief when they leave. The saying uses humor to make a point about human behavior, relationships and the effect people can have on the mood of a room. The quote is commonly attributed to Irish writer Oscar Wilde. However, the exact origin of the line is uncertain, and some researchers describe it as anonymous. Despite the uncertainty around its origin, the saying continues to be associated with Wilde because of its use of contrast and humor.
